The Formation Process
To understand where granite is found, we must first delve into its formation process. Granite is created deep within the Earth’s crust, where magma with a high content of silica and alkali metal oxides slowly cools and solidifies underground. This slow cooling allows the minerals within the magma to crystallize and grow, resulting in the distinctive coarse-grained texture that defines granite.

How Granite is Made: The Process Behind this Timeless and Resilient Stone

Granite, renowned for its strength and durability, has become a favorite choice for indoor and outdoor construction. This timeless and elegant material is not only resistant to acid rain but also adds a touch of sophistication to any project. But have you ever wondered how granite is formed and extracted? In this article, we’ll take a closer look at the process behind the creation of granite and the steps involved in extracting it from the earth.
Unveiling Nature’s Granite Factory
Deep beneath the Earth’s surface, lies a magnificent process that gives birth to granite. Boiling molten rock, known as magma, builds up immense pressure due to the intense heat. As a result, it rises through cracks and crevices in the Earth’s crust. As the magma ascends, it gradually cools and solidifies into granite, which is a type of igneous rock.
The Extraction Process
Extracting granite is a challenging task as the goal is to maximize the extraction while minimizing any damage. The process begins with outlining a section of the rock wall, typically up to 30 meters long and 7 meters wide. Long, narrow channels are burned into the rock using a gas flame to free up the sides. Deep holes, about 7 meters in depth, are then drilled along the back and bottom. Explosive cable is fed into these holes, and upon detonation, the section of granite is detached.
To further refine the section, a combination of drills, steel pegs, plates, and wedges are employed. This painstaking process continues until rough blocks measuring 3 meters long by a meter and a half wide and deep are obtained. Although small in size, these blocks each weigh more than 20,000 kilograms.
The Cutting Process
Once the rough blocks are transported to the granite factory, the first cut, known as slobbing, takes place. This process uses a specific type of saw that can cut slabs more than five centimeters thick. Synthetic diamond particles embedded in metal segments create the necessary friction to make the cut, while water prevents the saw from overheating. However, due to its slow nature, this saw can only cut less than two square meters of granite per hour.
For slabs thinner than five centimeters, a gang saw is utilized. This saw, with its sturdy steel blades, can withstand the pressure of cutting, ensuring a straight cut. The cutting rate of the gang saw is around eight square meters per hour.
Transforming into Beautiful Stone
After the cutting process, the slabs move on to the polishing line. This is where the true beauty of granite is revealed. The polishing line consists of 19 heads, each equipped with 6 bricks that polish through abrasion. Starting with the coarsest grit, the brick grains progressively get finer, resulting in a high gloss finish. The polishing line can process about a square meter of granite per minute.
However, depending on the desired finish, not all slabs go through the entire polishing process. For a semi-gloss finish, the slabs only pass through the first 10 heads. And for a rough finish, the slabs completely skip the polishing line and instead undergo a process called flaming. In this process, a propane flame at 2,000 degrees Fahrenheit is run across the surface of the slab, causing the quartz within the granite to explode. This creates a rough surface that is often used for non-slip flooring.
The Final Touches
The last step in the production of granite slabs involves cutting them to specific specifications. As granite is composed of various minerals that interlock like pieces in a jigsaw puzzle, the stone exhibits its trademark speckles and remarkable strength.
In summary, the journey from the depths of the Earth to the shining slabs of granite is a fascinating one. This natural stone, with its unique geological story in each location, leaves an indelible mark on the Earth’s surface. With its unrivaled strength and timeless charm, granite remains a beloved choice for construction and design projects worldwide.
“From the intense heat and pressure deep beneath the Earth’s surface to the meticulous extraction and cutting processes, the journey of transforming granite into elegant slabs has captivated mankind for ages.”
